You don't pass ldap_modify a filename, you have to pass it an array.  For
example (this forms takes the values from a form a modifies a given object to
match):

#ldap_person_attributes is just a local function that
#returns an array containing the values found in a
#person's LDAP object as key values
$person_attributes = ldap_person_attributes();
#ldap_get_uid is just a local function that returns the
#DN found when looking up "uid=$PHP_AUTH_USER and objectclass=posixaccount)
$user_dn = ldap_get_uid_dn($PHP_AUTH_USER);
$ds=ldap_connect("littleboy");
$r=ldap_bind($ds, $user_dn, $PHP_AUTH_PW);
printf("Binding to LDAP server as $user_dn<BR>");
if ($r) {
  printf("&nbsp;&nbsp;&nbsp;&nbsp;Bind successful.<BR>");
  $dn = urldecode($dn);
  printf("Operating on object %s<BR>", $dn);
  if ($action == "update") {
     $sr=ldap_search($ds,
           "$dn",
           "(objectclass=*)");
     $info = ldap_get_entries($ds, $sr);
     $person_uid = $info[0]["uid"][0];
     reset($person_attributes);
     for ($i=0; $i<count($person_attributes); $i++) {
       $key   = key($person_attributes);
       next($person_attributes);
       printf("<U>Checking attribute pair %s:%s to %s.</U><BR>",
         $key, $$key, $info[0]["$key"][0]);
       printf("&nbsp;&nbsp;");
       if ($info[0]["$key"][0] == $$key) {
         printf("<FONT COLOR=BLUE>");
        printf("Attribute pair %s:%s is unchanged.<BR>", $key, $$key);
        printf("</FONT>");
       } else
          {
           printf("<FONT COLOR=RED>");
           printf("Attribute pair %s:%s has changed.<BR>", $key, $$key);
           printf("</FONT>");
           printf("&nbsp;&nbsp;&nbsp;&nbsp;");
           if ((strlen($info[0]["$key"][0]) == 0)
                 and (strlen($$key) > 0)) {

                   printf("This attribute is a <BLINK>DELETE</BLINK>.<BR>");
                   $delete_entries["$key"] = "";
                  } else {
                      printf("This attribute is a <BLINK>CHANGE</BLINK>.<BR>");
                       $change_entries["$key"] = $$key;
